She was mad at me because I gave my friend a nickname in my contacts, but I didn't give her one. I told her time and time again that I didn't want to give her a nickname because her name is one-of-a-kind and absolutely gorgeous. I ended up giving her a nickname, but now she's mad I gave her a nickname.

I gave my friend one without asking. I asked if my girlfriend wanted one, then she got mad since I didn't ask my friend and I just gave it to my friend.

What does it mean?
